Prysmian Group new record in optical fibre data transmission | Prysmian Group

Prysmian, Nokia Bell Labs and the National Institute of Information and Communications Technology have achieved a record-setting 1 Petabit per second transmission over an optical fiber with standard dimensions. The experiment combines highly spectral efficient wideband optical transmission with an optical fiber guiding 15 spatial modes and the use of specific mode multiplexers. The total capacity of the network has been 1 Petabit per second, corresponding to simultaneous 8K-TV broadcasting for 10 million people.

The Switch to Online Everything: Fiber optic update for 2021

The pandemic changed everything: the way we work, teach, learn, attend conferences, shop and entertain ourselves. If we managed to avoid the virus, it even changed how we consult with our healthcare providers. “In person” became “online” for many of our everyday activities, putting a big strain on the world’s broadband networks. That the current network has been able to absorb all the extra traffic is miraculous, although the bulk of additional video calls, classes and other communications occurred during the day, which lessened the impact.

Fastest-Ever Internet Speed Could Download Whole Netflix in Seconds

The researchers from University College London achieved the new world record for the fastest internet of 178 terabits a second, which is five times faster than the previous world record held by a team in Japan and close to the theoretical limitations of the data transmission set out by American mathematician Claude Shannon in 1949. This means if that data connection were wired to your home broadband, it would allow you to download 22million HD photos in under a second, and download more than 220 4K-quality movies in a second.

How To Down-Select Colocation Candidates

To identify the most suitable colo candidates, many users begin with a simple web search referencing the desired geographical locations. Then, to shortlist the options, users generally evaluate candidates on 12 attributes, including capacity, reliability, efficiency, telecom, risk avoidance, managed services, financial stability, expertise, and costs. Factors most important to some enterprises, such as low cost or cloud direct-connect circuit availability, may be less important to others who might be focused on scalability or cooling density instead. Users must prioritize features and benefits when down-selecting candidate facilities for further consideration.

Sumitomo Electric secures submarine cable contract in Alaska

Sumitomo has been awarded a contract for the Stikine Crossing Submarine Cable Replacement Project from Southeast Alaska Power Agency (SEAPA). The project involves replacing a 138kV OF (Oil Filled) submarine power cable with an environmentally friendly 69kV XLPE (Cross-linked polyethylene) submarine cable with ancillary equipment for a fully functional system in the Stikine crossing (approx. 16,700 feet) between Vank and Woronkofski Islands, near Wrangell, Alaska, USA.
